Abstract:
A process for secured distribution of digital fixed pictures in the form of streams comprising sequences of data each containing a part of information of the picture comprising: modifying the original stream by modifying at least a part of the data sequences to produces a stream modified in the same nominal format as the original stream, transmitting the modified stream, and reconstruction of the modified stream with a decoder in addressee equipment, wherein the reconstruction is adaptive and progressive as a function of information coming from a digital profile of an addressee user.
